Study Notes
Pathway of Blood Through the Heart
- Blood enters the right atrium from the superior and inferior venae cavae and the coronary sinus.
- Passes from the right atrium through the tricuspid valve into the right ventricle.
- Flows from the right ventricle through the pulmonary valve into the pulmonary trunk.
- The pulmonary trunk divides into right and left pulmonary arteries, directing blood to the lungs for oxygenation.
- Oxygenated blood returns to the heart via pulmonary veins, entering the left atrium.
- From the left atrium, blood moves through the mitral valve (bicuspid valve) into the left ventricle.
- Blood is pumped from the left ventricle through the aortic valve into the ascending aorta.
- The aorta distributes oxygen-rich blood to the systemic circuit, providing nourishment to the body's tissues.
